Can you park at the bike park trails and ride after 4:30. Also is mountain biking possible on weekends when park is closed. Does it cost to use bike trails. Need info coming from Dallas wanted to ride bike

We've walked the bike trails late at night when camping. My favorite is the trail by South Dam campground. We saw mink, an owl and a beaver as we trekked along the shoreline. We hiked about 3/4 mile from the campground. We didn't see any bikers being close to midnight but lots of bike tire marks.

Yes there is parking at the trailheads. They are open on the weekends and after 430. There is a "$10" park fee.

There aren't any gates or anything into any of the parking lots that I drove through and I never even saw a sign posted saying that the park closes at dusk like I have seen at other parks before, people are in and out as there as there is tent and RV camping ( quite a lot of campers for March I thought, it gets pretty warm in the sun during the day but pretty dang chilly after dark and can be VERY windy with choppy waters) and there is no fee to ride and I don't know why my GPS told me that the park was closed on a Saturday but I still decided to drive there anyway and everything was completely open (like I said there aren't any gates) and the visitors center was open as well.
